Do big boobs increase cancer risk?

    Could having a larger than average bust make you more likely to develop breast cancer?

    According to a recent scientific study, that may be the case.

    The study, which consisted of 16,000 women, found genetic mutations associated with breast size were also linked to breast cancer, according to Australian newspaper, The Herald Sun.

    Some of the mutations involve regulating the female sex hormone oestrogen, which can trigger the growth of breasts and the growth of tumors.

    There have been other studies that have linked breast density to an increased risk of cancer, but there has not been much evidence linking breast size before. This study is the first substantial link.

    Much more research is needed before this evidence can be considered concrete, said Dr. Nicholas Eriksson of California-based genetics firm 23andMe.

    “Our results identify genetic variants that have an effect on both breast cancer and natural variation in breast size,” the doctor said. “While the precise relationships between breast size, density, obesity and breast cancer remain difficult to untangle, understanding the biology…may aid in the development of novel screening tools.”

    There are many other risk factors, outside of breast size, involved with breast cancer that must be taken into consideration such as weight, alcohol consumption and a strong family history.

    The recent findings do not mean that women with small breasts can assume they are safe, said the study’s lead author, Karin Michels, and all women are urged to go for breast cancer screening.
